Compact unit

Just 32mm high but with a measuring range of ±10kN, Kistler Instruments' Type 9129AA three component dynamometer is suitable for measuring the machining forces involved in drilling, grinding, milling and turning operations as well as general, multicomponent force measurement in confined spaces.

The materials used in the construction of the dynamometer are resistant to corrosion by cutting fluids and the unit is sealed to IP67 when used with the matching cable.

The design uses four multicomponent, piezoelectric, force sensors, which provide the three components of the force vector and the three components of the resultant moment vector. Forces are measured with almost no displacement and the design minimises temperature error.
